CEM微波合成用于Racemization的研究

更新時間：2012-06-29 點擊次數(shù)：2358

INTRODUCTION

One potential issue in peptide synthesis is racemization of cysteine and histidine. This is a concern for microwave peptide syntheis because of the elevated temperatures during deprotection and coupling. Studies have shown that lowering the temperature to 50 °C during the coupling of histidine and cysteine will decrease racemization.
